To all whom it may concern:

Be it known that I, Josnrrr G. Gms'rnvc, of San Francisco, in the countyof San Francisco and State of California, have invented a certain newand useful Improvement in Molding-Bars for Vaults, and do hereby declarethat the following is a full and exactdescription thereof.

My invention relates to an improvement in vaults so as to make them morefireproof and burglar-proof than has hitherto been the case.

It relates especially to the construction of the molding bars which areattached to the face of a vault for the purpose of giving the same afinished appearance and supporting the vault door when open.

' Hitherto, it has been found, that the bars when constructed of flatplates merely readily buckled and warped in case of fire, resulting; inpermitting the flame to pass behind the same and finally between thewall of the vault and the masonry inclosing the same. Experience hasshown that this is a very great disadvantage, as there is a tendency fora vault so constructed to be destroyed in case of fire.

My invention resides in the extension and strengthening of the moldingbars in such a way as to prevent their buckling in the manner abovedescribed, and also so as to prevent the passage of the flame behindthem. It will, furthermore, be seen that molding bars constructed -inaccordance with my inven tion, assist in protecting a vault from theattacks of burglars.

In the accompanying drawings: The figure is a cross-section takenthrough a vault equipped with the molding bars.

In the drawings 1 is a vault door which is supported in the front wall 2of a vault provided with molding bars 3 extending outwardly over themasonry of the surrounding wall. I attach to the rear faces of themolding bars 3, angular beams 4, each of which may be termed a recessangle. These angular beams 4 are secured to the molding bars in such away that one side of the angle constitutes a rearward right angularextensiton of each of the molding bars, which extends into the body ofthe masonry. That is to say, that the masonry of the surrounding wall islocated on either side of the said rearward extension.

In case of fire, because of the bracing effect of the angular beams 4,the molding bars will have practically no tendency to buckle, but willcontinue to lie flat and in close contact with the surrounding walls.Such being the case, the flame cannot, of course, obtain entry to thespace between the vault walls and the masonry walls contigu oustherewith. A vault so constructed will consequently more effectivelyresist the attack of flames. It. will also be seen that a constructionof this character will assist in resisting the attack of a burglar,inasmuch as the molding bars cannotbe readily pried off when they have areturn extension, such as that produced by the angular beams 4.

The molding bars 3 may be attached to the front of the safe 2, and theangular beams 4 may be secured to the molding bars 3 in any suitablemanner, such as by welding, brazing or riveting.

I claim 1. In a device of the character described, the combination of avault, one or more molding bars united therewith, and strengtheningmeans united with said .bar or bars, comprising one or more angle beamsadapted to prevent the molding bar or bars from buckling.

2. In a device of the character described, the combination of a vault,one or more molding bars united therewith, and strengthening means,comprising one or more angle beams attached to the molding bar or barsfor preventing the latter from buckling.

3. In a device of the character described, the combination of a vault, amolding bar united therewith, and strengthening means united with thebar for preventing the bar from bucklin said strengthening meanscomprising a plate located in a plane sub stantially at right angles tothe front of the vault. and directed toward the rear thereof.

4. In a device of the character described, the combination of a vault,one or more molding bars united therewith, and strengthening means,comprising one or more angle beams attached. to the outer edge or edgesof the molding bar or bars for preventing the latter from buckling.

5. In a device of the character described, the combination of a Wall, avault located therein and having its opening parallel With the Wall, oneor more molding bars upon the vault also parallel to the Wall, andstrengthening means, comprising one or more angle beams forming arearward right-angular extension at the outer edge or edges of themolding bar or bars adapted to prevent the latter from buckling. 10 Intestimony that I claim the foregoing I have hereunto set my hand.
